Referring to the attached figure 1, the invention discloses an elevator dispatching method, which comprises the following steps: obtaining a plurality of target stop floors of an elevator; detecting the floor where the elevator is currently located in real time, and controlling the elevator to continuously run to a standby floor when detecting that the elevator is currently located at the last target stop floor
So that the a elevators are uniformly stopped up and down, and the standby floor is the middle stopping floor. Wherein n belongs to (0, 1, a-2, a-1), and the value of n is substitutedThe elevator is shown in the table, wherein a is the number of elevators capable of operating, and b is the number of floors capable of operating.
For example, in a preferred embodiment, a building is provided with three operational elevators, a equals 3, and from 1 to 21 floors, b equals 21. The values of n of the standby floors corresponding to the three elevators are 0, 1 and 2 respectively, namely L when n is 0, 1 and 2 respectively(n)In the case of the multi-span building,
roughly, the standby floors of the three elevators of the building are 3.5, 10.5 and 17.5, and it is understood that the first standby floor can be 3 floors or 4 floors, the second standby floor can be 10 floors or 11 floors, and the third standby floor can be 17 floors or 18 floors.
The uniform landing strategy is illustrated below by a few specific building floors and elevator numbers.
Referring to fig. 1, the illustrated building has 15 floors, i.e., the runnable floor b of the elevator is 15, 1 elevator, i.e., a is 1, the standby floor of the building is 8 floors, and the number of floors from 8 floors to the bottom floor 1 and the top floor 15 is the same, i.e., the intermediate floor.
Referring to fig. 2, the illustrated building has 15 floors, i.e., 15 floors b, where elevators can travel, and 2 elevators, i.e., 2 floors a, are provided. 15 floors are divided into 1 to 7 floors of low floors and 8 to 15 floors of high floors, the standby floors of the building are 4 floors of low floors and 11 floors of high floors, namely, the number of floors from 4 floors to the bottom floor 1 and the number of floors from the top floor 7 are the same, the number of floors from 11 floors to the bottom floor 8 and the number of floors from the top floor 15 are only one floor different, the number of floors can be considered to be the same, and therefore 4 floors and 11 floors are intermediate floors.
Referring to fig. 3, the illustrated building has 15 floors, i.e., 15 floors b, where elevators can travel, and 3 elevators, i.e., 3 floors a, are provided. The 15 floors are divided into 1 to 5 floors of the lower floor, 6 to 10 floors of the middle floor and 11 to 15 floors of the upper floor, the standby floors of the building are 3 floors of the lower floor, 8 floors of the middle floor and 13 floors of the upper floor, namely, the number of floors from 3 floors to the bottom floor 1 in the lower floor is the same as that to pass through the top floor 5, the number of floors from 8 floors to the bottom floor 6 in the middle floor is the same as that to pass through the top floor 10, and the number of floors from 13 floors to the bottom floor 11 in the upper floor and that to pass through the top floor 15 is only one layer different from that to pass through, so that the 3 floors, 8 floors and 13 floors are the middle floors.
Preferably, in order to calculate a more direct calculation result, the pair
Zero-removing and rounding, and pair
Zero-removing and one-rounding are added, so that the a elevators can stop up and down uniformly and are inclined to stop at a high floor. For the preferred embodiment described above, then
Preferably, a minimum moving strategy is required during elevator dispatching, namely all elevator running paths are minimum, specifically, the total running distance of all running paths of the part a of elevators running to the a standby floors respectively is calculated, the running path with the shortest total running distance is selected as a target running path, and then the part a of elevators are dispatched to the a standby floors respectively according to the target running path.
For example, in the above preferred embodiment, if one elevator runs to floor 1 after people are loaded, and the other two elevators are located at floors 6 and 11 respectively, the elevator closest to the waiting floor is selected to run to the waiting floor according to the conventional thought, but if the elevator is dispatched according to the conventional thought, the total route of the three elevator runs is 19 floors.
If the minimum movement strategy is adopted, the elevator at the floor 1 is dispatched to run to the floor 4, the elevator at the floor 6 runs to the floor 11, the elevator at the floor 11 runs to the floor 18, and the total path of the three elevators is 15 floors and less than 19 floors.
In distinction to the above-described minimum movement strategy, the invention can also use another scheduling strategy, called minimum movement strategy, in view of the travel loss of the elevator from a stationary state to a moving state, i.e. when the elevator has delivered a load to the destination floor, it continues to travel to the remaining standby floors of the a standby floors. Specifically, in the above preferred embodiment, if one elevator runs to floor 1 after people are loaded, and the other two elevators are located at floors 4 and 11, respectively, and the other two elevators are already located at the standby floors, only the elevator at floor 1 needs to be dispatched to the standby floors of the remaining 18 floors.
In addition, in the foregoing minimum movement policy, the minimum movement policy may also be combined, specifically, if the number of the remaining standby floors is greater than 1, the total travel distance of all the travel paths in which all the elevators not reaching the standby floor currently travel to the remaining standby floors respectively is calculated, the travel path with the shortest total travel distance is selected as the target travel path, and all the elevators not reaching the standby floor currently are dispatched to the remaining standby floors respectively according to the target travel paths.
For example, in the above-described preferred embodiment, if one elevator runs to floor 1 after the completion of the manned elevator, another elevator runs to floor 6 after the completion of the manned elevator, and another elevator is located at floor 11 on the standby floor, the elevator located at floor 1 is dispatched to floor 4, the elevator located at floor 6 is dispatched to floor 18, and the elevator located at floor 11 is stationary, and at this time, the total travel route of both elevators is 15 floors. An elevator at floor 6 is dispatched to floor 4 and may run 4 floors less than an elevator at floor 1 is dispatched to floor 18.
Preferably, in order to reduce the amount of calculation, one of a standby floors can be set for a elevators as a dedicated standby floor for each elevator, and after the elevator transports the carried object to the target floor, the elevator respectively continues to run to the dedicated standby floor.
For example, in the above preferred embodiment, the special floor of elevator 1 is 4 floors, the special floor of elevator two is 11 floors, the special floor of elevator three is 18 floors, elevator 1 is located at 10 floors after people are loaded, elevator two is located at 1 floor, and elevator three is located at 13 floors, at this time, elevator 1 is directly operated to 4 floors, elevator two is operated to 11 floors, and elevator three is operated to 18 floors without considering the minimum movement strategy and the minimum movement strategy.
Preferably, considering that the elevator is possible to be used by people on the current floor after the elevator is stopped to carry people, when the elevator is conveyed to the target floor by the carrying piece, the elevator needs to stay on the target floor for a preset time period and then continuously runs to the standby floor, but the elevator does not directly run to the standby floor after the elevator door is closed.
The invention also discloses an elevator dispatching system, which comprises a central control module and a plurality of elevator modules, wherein each elevator module comprises an operation control unit and an elevator car, and the operation control unit is connected with the elevator car and used for controlling the elevator car to operate in the elevator shaft. The central control module is respectively connected with the elevator modules and used for controlling the operation control unit so as to dispatch the elevator cars. Each building has a operable elevator cars, and the standby floors of the a elevator cars are respectively
And the central control module controls the elevator car to continuously run to the standby floor according to the elevator dispatching method after the elevator conveys the carried piece to the target floor.
It should be noted that the embodiments of the present invention have been described in terms of preferred embodiments, and not by way of limitation, and that those skilled in the art can make modifications and variations of the embodiments described above without departing from the spirit of the invention.
